7 Claims. This invention relates to alves. of the type employed in dispensing lacquer or'similar substance from containers, and the primary object is to provide a specially formed valve assembly which may be attached to conventional lacquer containers so that the longitudinal axis of the valve is disposed at an angle to the. end of the container in order that substantially all of the liquid therein may be withdrawn when the valve is disposed horizontally.

Another important aim of the instant invention is the provision of a valve assembly for lacquer containers that is particularly useful when the container is mounted upon on inverted rack of the conventional form which is now employed in the paint industry by color mixers.

Another important object of the invention is to provide a dispensing valve for containers which comprises a hollow body through which is transversely passed a specially formed valve stem having threads thereon, which threads are in the cavity within the hollow body when the valve is closed so that vapors and fumes from within the container may constantly envelop the threads for the purpose of precluding such hardening of the lacquer or paint thereon as would render the valve inoperative after the same had remained unused for an appreciable length of time.

An even further object of the invention is to provide a dispensing valve for containers of lacquer or the like, which has a specially created valve stem one end thereof being provided with a spherical face, a portion of which is projected beyond the hollow body of the valve when in the closed position.

Paint manufacturers and distributors find it necessary to specially mix certain colors of lacquer and paint to meet the requirements of the trade. To accomplish this end, a large number of basic colors are kept in containers which are mounted in racks for the purpose of tipping the containers or inverting them completely to prevent settling during the hours of inactivity. Small quantities of lacquer or paint are drawn from the containers of basic colors and the said quantities thoroughly mixed to produce the desired shade.

The color mixer finds that where valves of the ordinary character are employed, the outlet port thereof usually becomes clogged or filled with hardened lacquer or paint to the extent that drawing the liquid from the container is entirely precluded, In common types of valves it has always been found that the lacquer or paint will oa th read o the va e. tamped ender 'Mo., a corporation of Missouri 1938, Serial No. 223,711 (Cl. 221-22) d l its turning o openv andose he valve- In other instances, valves have been applied to containers so that when the valve is in the normal position for drawing lacquer or paintfrom the container, none is available; through the out-. let port of the valve, yet there still remainsin the container a quantity of the lacquer or paint which must be drained therefrom through some other action than by manipulating the valve.

Thevalve and its special associationwith cone 1 ventional containers embodying the concepts of this invention is intended to overcome the foregoing shortcomings and meet the problem's Dresented in an efficient, economical and desirable manner. The preferred embodiment of the invention is illustrated in the accompanying drawing wherein:

Figure 1 is an end elevation of a conventional lacquer of paint container equipped with a valve assembly made in accordance with this; invention.

Fig. 2 is a vertical central sectionthroughthe valve assembly and portions of the container taken on line HII of Fig. 1. b

Fig. 3 is a side elevation of the valve showing the same attached to a container which hasbeen tipped; and,

Fig. 4 is an enlarged fragmentary detailed sectional view through one end of the'valve stem and the seat therefor at the outlet port. so

'I?he conventional type gallon container 6 has a flat end wall 8 from. which projects a neck It provided with screw threads l2. The-free end of neck It) has an internal flange l4 uponwhich may-be seated a well-knowngasket orwasher; if such is necessary to preclude leakage when applying the valve to neck It].

A collar 5 having a screw threaded-annu ar wall It engages threads l2 of neck Hlwhenitis; desired to secure the valve in the operative po-- sition. Annular inturned flange 2i! forming a part of collar I6 is movedagainst the-outer face of plate 22, the inner face of whichrests directly against flange M or the gasket carried thereby.

Hollow body 24 may be integral ,with plate 22 or otherwise formed rigid therewith sothat itis, positioned eccentrically to the, axis ofjthe, plate, and very near the edge thereof. Cavity 26- formed in-body 24 is in communication-withgneck nd. h f re, with the-interior of container 6, so that the lacquer or other liquid. in container 6 may flow directly into cavity. 26 and thence therefrom through outlet port'28 which is formed hrou h. he; annularv wall of: body. 241

shallow-b95513! is created. in that. portion. or

the wall of body 24 wherein outlet port 28 is formed. An internally threaded boss 32 integral with body 24 and diametrically opposite boss 30 receives valve stem 34 upon which is provided screw threads 36 which engage the internal threads 38 of boss 32.

Packing 40 and packing nut 42 complete the means of maintaining valve stem 34 in the operative position where it may be rotated to move the spherical head 44 thereof toward and from a position closing outlet port 28. This spherical head 44 is formed upon one end of valve stem 34 while a handle 46 is provided at the other end thereof.

The spherical surface 48 on head 44 engages seat 50 which has a contour complementary to that portion of surface 48 which moves thereagainst when the valve is closed. That portion of surface 48 beyond seat 50 is projected outwardly from body 24 through outlet port 28 and therefore may be quickly cleaned by the operator because when the assembly is in the position illustrated in Fig. 3 and the valve is closed, any collected lacquer or paint will form at the extreme end of valve stem 34 in the nature of a globule and the remaining portion of the projected spherical face 48 will free itself from any collection of the material being dispensed.

Plate 22 is disc shaped and hollow body 24 is a thimble-like structure which should be positioned at the lowest portion of disc 22 when the valve is attached to container 6 for use as is the custom when employing tipping racks for the containers. Collar l6 may be turned to tighten plate 22 when hollow body 24 is located as desired. When this collar i5 is turned, plate 22 and its associated parts need not be rotated and therefore quick and efficient attachment to the conventional container 5 is permitted.

The horizontal axis of hollow body 24 extends outwardly from plate 22 at an angle of the plane of said plate. This angle is preferably as illustrated, so that when outlet port 28 and the axis of body 24 is on a horizontal plane, the central longitudinal axis of container 6 will extend upwardly and outwardly from the valve. In other words, if the longitudinal axis of hollow body 24 is extended, it will intersect the side 52 of container 6 close to the line of attachment between side 52 and end wall 8.

In Fig. 3, body 24 of the valve assembly is in the position where the operator is drawing liquid from container 6 and causing such liquid to enter a small container 54 which is positioned upon any suitable support below the valve. This container 54 should be carried by a horizontal support, for in this business, measuring instruments are employed to insure accuracy and therefore the container 54 must be placed as just set down.

' liquid is withdrawn when container 6 is in the inclined position illustrated in Fig. 3, and the rack holding the container 6 maintains the said container in the position shown solong as it is desired to withdraw liquid therefrom. Manifestly, when container 6 is inclined as shown, and thevalve is in the proper position thereon, a very small amount of liquid need be left in the container when the valve can no longer withdraw liquid therefrom. Such disposition of valve and container therefore not only insures that practically all of the liquid is withdrawn from the container when the valve is in the normal position (Fig. 3) but the position of valve stem 34 and handle 46 is always the same and convenient to the operator.

One skilled in the art will find additional advantages when using a dispensing valve made in accordance with this invention, and while the preferred embodiment has been illustrated and described, it is desired to be limited only by the scope of the appended claims.
